.therebelow, in the centers of which v'is xed a 'ijf' vertical shaft 16. The :top peripheral edgel 3 ,of the pedestal is :provided with transversely aligningreeesses 7 v and A8xfor receiving horizontal bars or tongues as .at 9 formed integrally thennder side ,of a `disc .11

provided with a central 'opening 12 for the shaft 6 and having an upstanding peripheral iiange The disc 11 is thns held :against rotation,y and fatthe center thereof is yan np- -standing boss '14, upon the top of which restsv ,a ballebeari-ng cage 15 for rotatably support- .ing an. inverted -boiwlashaped casing 16 yhav.-

ing-:a .central opening 417 through itstop 18 for .the shaft 6.'

Fixed to the top 18 of the casing-1,6 and --rotatably mounted vupon the shaft .6 is va hub 19 carrying a trame 20 and arms 21. For preventing backward rotation of the arms 21,

the following mechanism is provided. A

locking plate 22 having an opening 2.3 for receiving the :boss 14 is adapted to :loosely rest upon the surface A2416i the disc 11. `livotally supported by the locking pla-te 221at25 and -26 are a pair of' oppositely arranged pawls 27 and 28 having toothed ends 29 and 30 v s Yvfvhich'arfe adapted to ,engage vertical teeth 31 on the inner surface Aof the npstanding -peripheral flange 13 ofthe stationary ydisc/111. The pavvls 27 and 28 have right angular and inwardly extending heads indicated by 32 `and 33, which are adapted to beengaged by side edges of transversely aligning vertical recesses 34 and 35 cfa depending .circular flangeY 36 formedintegrally With-thetop '18 of the casing 16. VS t i1`oss37 and 38gcarried u by the dise 'l1-are adapted to be engaged yby the pa-Wls L27A and 28 when the lcasing'l `ro tates clockwise. -Whentheeasingfl6 rotates in the opposite direction, the pawls 27 and 28 are caused to swing away from .thev stops .37 and 88 and theirtothed ends-29 and 30 to engage the teeth B1 and thereby prex'fentY backward Vrotation of said easing and the arms 21 carried thereby. e

In. .Order to cause automatic rotation of the y arms 21 after initial movement thereof by a person pressing thereagainst, and also to Vautomatically check said movement at its end to eliminate noise in operation and to stop having a rod 52- which extends througlif a central opening 58 of a cap 54 :for the cylinder. To the projecting end ofthe rod 52 isiixed a head 55,1which supportsa bar 56 pivotally connected to the crank-pin 57 of a crank-58. VSaidcrank is Xedto theV shaft '59 fof a bevel pinion 60, and said shaft is rotatably supported in the sides of' a bracket formed integrally with the uppery end ofthe baselplate 43." The bevel pinion 60.2and a similar bevel pinion 61 supported by the base plate 44 mesh with the'ring-gear 42 andthe 'cranks 58'and 62 are fixed tothe shaft-s'thereof at right angular positionsrelative to each other; A'pair of contractual coiled springs 63 and 64 extend from cross-arms 65 and 66 at the base of the cylinder 47 tocrosslarms 67 and 68 carried by the head 55V tend to force the' pistoni rod 52- downwardly for Acausing continued rotation of: thejturnstile arms :'21 tothe quarter lposition after vthe initial manual operationfthereof. The arms ofthe turnstile stop on thejquarter position due to the crank 58 returning to its originalrdownward and vertical position and the coiled springs 63and`64 pulling :directly againstthe dead center thereof.Vv The cylinder 48 is simi-` lar I to the' cylinder 47V and,l slidably mounted therein is a piston 69, the rod 7 0. of which is pivotally connected to the crank 62, but there are no coiled springsy foractuating the piston rod downwardly. i ii When the arms 21 of the-turnstile arealmost -to ythe limit oflthe quarterV turn, the rotation vthereof ischecked by thefpistons'l and 69moving downward-ly against airlpressure in the cylinders47 and 48. fAt the be-l ginning of the upward movement ofsaidpistons, lair is admitted tothe cylindersy below each piston through a vent 71f'wl`1ichfregisters with a slot 72 of the hollow trunnion` 45er 46. Thevent 71 is enlarged at 7 3 to provide a chamber and a seatpfor'a balli-check valve 74.` A vented plug 7 5 is liXed in and closes said chamber; In the-downward movement of thepistons, thevents 71 are closed byl the check valve 74, and. theiair is forced V.outfof each cylinderslowly throughl aby-pass-76 'my invention may of proper size to produce the desired movement of the arms 21 of thel turnstile. The by-pass 76 registers with a slot 77 of the hollow trunnions, and an opening 78 establishes free communication between said trunnions and the atmosphere, A; vent 79k with check valve 8O is provided in each of the caps 54, and airV escapes froml the cylinders throughmthese vents when the pistons move upwardly but is prevented from entering on `the-downward movement of the pistons. In

ordervto break the vacuum above the pistons so that the pistons may move downwardly, anfinlet opening 81 is provided in each cap 54, and said inlet openings are closed by an adjustablevalve as for'instance 82' for mitting air at a desired speed. 1 y

Operation: Assuming that the arms 21 of theturnstile Vare at rest on the quarter `turn and also the other parts are asshown, anda person walking thro-ugh, indicated by the arrow, presses againstwthe left 'arm of the turnstile. Saidfarms will be rotated by said pressing action just beyond one-eighth of a revolution, which` movement will cause lthe ring-gear 425 to rotate` the Vbevel. pinions ad-A and 61 to actuatethe'cranks58 and 62 `inst beyond one-half of"arevolution. At .they vsame time, the pistonil will travel upward- 1y for its full movement and the piston 69 will travel downwardly from its central positionand then upwardly to the same position. Aspsoonas the crank 58 passes the upper dead center, the coiled springs 63 and 64 willV forcey the .piston rod 52 downwardly thereby automatically continuing the rotation of the arms 21of the turnstile. :As the piston travels downwardly, it works against and forces air through the by-pass 76, which hasa cushioning effect upon and cheeks the movement ofthe arms of the turnstile to their quarter positions. The arms of turnstile come to a stopat their quarter positions when the crank-58'h`as returned to its original or lower deadcenter-position.

From the drawings and description,=it will be readilyseenthat" after initial manual rotationofthe arms ofthe turnstile, the movement thereof willjbe'continued and come to a stop at their quarter positions, and that before" the arms come to a stop, the movement roo thereof will be' gradually retarde-d and i checked fr thereby preventing noise in operation of the turnstile.

, It will be understood thatsliglit changes in the details of construction'for carrying'out beA made; within the scope ofthe claims.
